Hi, I bought my first diesel and its a 2014 Ram 1500 3.0 Ecodiesel. I would like to change the oil in it myself and have watched many video's. I would like to know the best oil to use. I would like this truck to last for a very long time. The manual calls for ACEA C3 5W30 or Pennzoil Ultra Euro Full Synthetic 5W30. What does the best job?
